Temperature Sensor and the Scope Display Tab
The internal temperature sensor on the ADS130E08 is shown in Figure 22.
When the internal mux is routed to the temperature sensor input, the output voltage of the ADC may be
converted to a temperature value using
Temperature ( C)
The output voltage corresponding to a given temperature can be read by running a data acquisition after
the Temperature Sensor mux option is selected, as shown in the
Figure 18
demonstrates an example of temperature sensor readings read back using the GUI.
